I am using one BT878 (conextant fusion 878A based) 4 inputs card on an Ubuntu 12.04 server version. I have a problem to watch video from several inputs of BT878 card. I can only watch video from channel/input 0. For all the rest channels/inputs I only watch a black image which includes date and hour information. I had followed all the suggestions of the Pico2000 wiki but it did not work.
These are the screens that I can watch:
- Screen shot channel input 1
- screen input one.png (33.22 KiB) Viewed 1244 times
- Screen shot channel input 0
- screen input zero.png (130.84 KiB) Viewed 1244 times
These are the outputs that I get from the following commands:
lspci -s 01:06 -v
